Bug#677211: [grub-pc] Segfault on "grub-probe --target=device /missing"

[Sebastian Pipping]

Package: grub-pc
Version: 1.99-21
Severity: normal

--- Please enter the report below this line. ---
grub-probe segfaults when queried for missing files or folders

$ /usr/sbin/grub-probe --target=device /missing
Segmentation fault

which makes update-grub2 fail inside a chroot as a consequence.
However, the above command fails outside of the chroot, too.
